To all whom it may concern:

Be it known that I,-ALoi izo E. LEWIS,OIE

Ingersoll, in the county of Oxford, inthe,

Provinceof Ontario, Canada, a subject of the King ofrGrreat' Britain,haveiinvented certain new and useful Improvements in Resilient Heels,ofwhich the followingis a specification.

This invention relates to the heels of boots and shoes, and my object isto produce a heel which will be more. elastic than the ordinary rubberheel without the sacrifice of strength and durability. I attain myobject by with an internal spring cushion and means for distributing thepressure of the cushion so that there is no localized pressure below jthe wearers heel, and no concentration of wear at the middle of thetread surface of thejboot heel.

The invention is hereinafter more specifi-j. cally described and isillustrated in the ac companying drawings in which-- 3 7 Fig. 1 1s alongitudinalsection of part of the shoe with my lmprovedheel 1n posi-Fig. 3 a plan View showing a modification.

I; In the drawings like numerals of reference,

indicate corresponding parts in the different figures.

fl is a heel preferably formed of a'rubber' compound or other relativelysoft and resilient composition, which is securedto the leather lift 2'of the shoe by the nails 12 and washers 13 which are embedded in therubber at a level above that of the bottom of the recess 3. Centrally ofthis heel is formed a sarinw cushion which isada ted to bear against therubber heel, and also against the lift of the heel 2 ofthe' shoe.

By the substitution of an elastic cushion for.

. the solid rubber of an ordinary; rubber heel a much greater degree ofresiliency is maintamed than 1s possible wlth such heels withv outsacrificing any of the wearing qualities. This cushion ispreferablyformed as follows. A-recess 3 is formed in the heelex-l tending partwaydown from thetop there- Application filed Ju1y 18, 1921. Serialno.4aa520.

.of. In thisrecess is'located a coil spring 4 against the shoe heel 2 Todistribute the pressure, itis preferable to mold in the rubber heel, atthefbottom of the recess, a th n metal Jplate,5,;and asimilar metalplate '6 is provided against the upperend of the coil spring bearing. Itis also preferable to recess th hel 2 to partly receive the coil spring4, as thisl way a longer and there fore a more equably acting coilspring may. bev employed. While If prefer to use one I I spring, yet aplurality of recesses and a pluproviding the heel rality of springs maybe employed as indieatedin Fig. 3, and such a construction" would fallwithin the scope of my invention.

a pressure distributing plate fitted over the 7 upper end of the spring.
